A multilayered waveguide holographic memory media consists of a stack of single-mode slab waveguides. An UV embossing process has been developed for fabricating this structure. This process is suitable for mass production at low cost, but it is has a disadvantage of poor precision in the control of layer thickness and data position. The distribution of the core inclination and the error in data position alignment were checked, and the results showed that this process is sufficiently accurate for fabricating the above media. Also, the durability of the media fabricated by the UV embossing process was tested. The media was preserved under high-temperature and high-humidity conditions (80°C and 85%RH respectively). The results showed that this media has sufficient durability for practical use.
